x+3y = 4
3x-4y = -1;
плиз помогите
3х+у=5
5х-2у=12
​

Answer 1

Ответ:

1) $x + 3y - 4 = 0$

2) $3x - 4y + 1 = 0$

3) $3x + y - 5 = 0$

4) $5x - 2y - 12 = 0$

Пошаговое объяснение:

1) $x + 3y = 4$

$x + 3y - 4 = 4 - 4$

$x + 3y - 4 = 0$

2) $3x - 4y = - 1$

$3x - 4y + 1 = - 1 + 1$

$3x - 4y + 1 = 0$

3) $3x + y = 5$

$3x + y - 5 = 5 - 5$

$3x + y - 5 = 0$

4) $5x - 2y = 12$

$5x - 2y - 12 = 12 - 12$

$5x - 2y - 12 = 0$
